Expected ')' (to close '(' at line 1), got <eof>

What the message means

ServerScriptService.KillBrick:4: Expected ')' (to close '(' at line 1), got <eof>

Other forms of the same message:

• Expected ')' (to close '(' at line 3), got 'local'
• Expected '}' (to close '{' at line 1), got <eof>
• Expected ']' to match an opening '['

Brackets come in pairs: ( ) for calls and grouping, { } for tables, [ ] for keys. When Luau reaches something that cannot be inside the open bracket, it stops reading and reports the bracket it was still waiting to close.

The line number at the start of the Output line is where Luau gave up, which can be much further down. The number inside the message, at line N, is the one to go to.

Causes and fixes

Three things cause this error in practice. Each one below has the smallest code that triggers it, then the fix.

• end instead of end) after Connect(function()
• A call or a string inside it is not closed
• A table is missing its } or a comma

end instead of end) after Connect(function()

part.Touched:Connect(function(hit) opens a bracket for Connect, then a function. The function closes with end, and the call still needs its ).

local part = script.Parent

part.Touched:Connect(function(hit)
	print(hit.Name)
end

Close the call after the function: end).

local part = script.Parent :: BasePart

part.Touched:Connect(function(hit: BasePart)
	print(hit.Name)
end)

A call or a string inside it is not closed

A print( or Vector3.new( missing its ) makes Luau read the next line as part of the call. A missing closing quote does the same, and Luau reports both.

local part = Instance.new("Part")
part.Position = Vector3.new(0, 10, 0
part.Parent = workspace

Add the missing ) at the end of the call.

local part = Instance.new("Part")
part.Position = Vector3.new(0, 10, 0)
part.Parent = workspace

A table is missing its } or a comma

The same rule for tables: { needs }, and items inside need commas. A missing comma gives Expected ',' after table constructor element first.

local settings = {
	WalkSpeed = 16,
	JumpPower = 50
	Gravity = 196.2,
}

Put a comma after every item (one after the last is allowed), and close the table with }.

local settings = {
	WalkSpeed = 16,
	JumpPower = 50,
	Gravity = 196.2,
}

return settings

How to find the line that causes it

1. A syntax error stops the whole script before its first line runs, so nothing in that script works, not just the broken line.
2. Open the script. The Script Editor underlines the problem in red; hover over the underline to read the message.
3. Open Script Analysis (View tab) to see every syntax error in every script, with its line number. Double-click one to jump to it.
4. The line number in the message is where Luau gave up, which is often below the real mistake. The (to close ... at line N) part points at the line where the unclosed bracket or block starts.

How the code was checked: every block marked Fixed passes Luau's strict type checker against Roblox's API definitions (luau-lsp, 23 October 2026), and every block marked Breaks compiles only to fail with the message on this page. The message wording was checked by compiling each broken block on this page with luau-compile, which uses the same Luau parser as Roblox Studio, on 23 October 2026. A type check catches misspelt APIs and wrong types, not game logic, so playtest in Studio before you publish.
